Michelle Monaghan wore a gorgeous teal dress by Roksanda Ilincic at the Cinema Society and Coach screening of her new film, "Source Code," in New York on March 31.

The U.K. designer is clearly becoming a favorite of Hollywood's starlet set -- check out Elisabeth Moss in a nude gown by the designer at London's 2011 Olivier Awards earlier this month -- and we think this sleeveless dress with origami-style asymmetric folded skirt looks fantastic on the red carpet.

Monaghan is right on trend (well, actually ahead of the curve) with the teal hue -- according to Pantone, Deep Teal is Fall 2011's top color. The "Source Code" star accessorized the dress with a Jimmy Choo clutch, fierce black leather sandals and cutie co-star Jake Gyllenhaal by her side (Lindsay Lohan also made an appearance on the red carpet).

Monaghan wore her hair and eye-skimming bangs sleek and straight, and added some peach blush and nude lipstick.
